Answer:

Answer A, 4x^2-2x-10

Step-by-step explanation:

Since we are subtracting the first listed equation from the second, we have to switch the order of those two. The second row will all become negative (just the second, not the first) since this is subtraction. You add the numbers from there and remember to keep your coefficients and variables in line (x^2 to x^2, x to x, etc.)

A town has a population of 13000 and grows at 4.5% every year. What will be the population after 13 years, to the nearest whole
hodyreva [135]
23,039. 
y=13,000(1.045)^t
t=13
You get 1.045 because you add 1+ the percentage in decimal form.

Use the sample data and confidence level to construct the confidence interval estimate of the population proportion p. n equals
Alekssandra [29.7K]

Answer:

(0.767,0.833)

Step-by-step explanation:

The 95% confidence interval for population proportion p can be computed as

p-z_{\frac{\alpha }{2} } \sqrt{\frac{pq}{n} }

The z-value associated with 95% confidence level is 1.96.

whereas p=x/n

We are given that x=440 and n=550.

p=440/550=0.8

0.8-1.96\sqrt{\frac{0.8(0.2)}{550} }

0.8-1.96\sqrt{\frac{0.16}{550} }

0.8-1.96\sqrt{0.00029 }

0.8-1.96(0.01706)

0.8-0.03343

0.76657

Thus, the required confidence interval is

0.767<P<0.833  (rounded to 3 decimal places)

Hence, we are 95% confident that our true population proportion will lie in the interval (0.767,0.833)
